"There was water pouring from the second floor to the first floor," Marzouk said.

Marzouk believes it was an accident, but damage estimates now top $10,000.

"The place is destroyed," she said.

She says Airbnb was slow to respond when she called to report the damage, but worse is that she didn't realize who the renter was. The woman renting the room told Marzouk she was a real estate agent, but things didn't add up.

"As the pieces fell into place that she was more than likley using my bathroom as a business for her to take photos of herself," Marzouk said.

Marzouk believes her guest was a sex worker who left behind sex toys and installed extra lighting in the bathroom, and left behind a handwritten shot sheet, too X-rated to show, of sexy pictures she was possibly planning to take.

"I gave my key to someone who Airbnb didn't check their ID," she said.

In a statement, Airbnb said: "We have zero tolerance for this kind of behavior and have removed this guest from our platform."

Airbnb offers safeguards. It says hosts can verify ID on its website, requiring guests provide a government ID.

Marzouk says her guest is now gone and Airbnb says it is working to cover the cost of damage.
